.AN'IISKIDDIN G ATTACHMENT FOR WHEELS.

Specification of Letters Patent.

Patented Feb. 13, 191?.

Application filed January 19, 1918. Serial No. 72,927.

To all whom it may concern:

Be it known that I, Lnnwrc FRIEDRICH, a

citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Antiskidding Attachments for Wheels, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to means for attaching antiskid devices to the wheels of power driven vehicles, and the object thereof is to provide improved devices of this class which are simple in construction and strong and durable in use and the application of which is simple and may be accomplished in a short time; and with this and other objects in view the invention consists in a device or devices of the class specified, constructed and applied as hereinafter described and claimed,

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a cross section of the rim portion of a wheel and showing my improvemcnt applied to one of the spokes of the wheel;

Fig. 2 a cross sectional view of one of the spokes ol a wheel and looking in the direction of thearrow 2 of Fig. 1 andshowing the method of applying my improvement to the. spoke; and,

Fig. 3 a view similar to I ig. 2- but showing a modification.

In the drawing. I have shown for illustration at a a part of the rim of a wheel and at I) one of the spokes connected therewith and, in the practice of my invention, I provide a yoke piece 0 having, in the form of construction shown, a central longitudinal slot 0 and provided at one end with a circular hook member (1 and at the other end with an ordinary snap'hook r." having and bolts 6 are passed through the slot 0 and through the ends-of the plate d and provided with nuts 6 and by means of this constructior the yoke icce 0 may be bound securely to the spo e adjacentto the rim portior. of the wheel by providing a longitudinal slot in the yoke member 0, said member is adapted for use in connection with s} okes of various sizes within certain limits.

I also employ in connection with my improved attaching device the usual chain I, one end 01 which is adapted to be connected with the hook member a of the yoke member 0 as shown at f and said chain is passed around the rim and tire or tread member which is not shown and connected with the snap hook c as shown at f, and the device is' ready for use, and while I have showr. but one of my improvements applied it will be understood that any do sired number thereof may be employed in connection with the spokes of a wheel.

The end portions of the bolts 6 where they pass through the yoke-member a are provided w th angular parts e, and the top and bottom walls of the slot c are provided with angulnrre'cesses 0 adapted to' receive the angular portions 1; of the bolts 6, and by means of this construction the bolts are prevented from turning in the operation of applying tie nuts 1: and are also made adjustable 1oward and from the spoke.

The modification shown in Fig. 2 is the same in all respects as the construction in Figs. 1 and 2, except that the spoke b is approximately round or elliptical in cross section, an( for the straight plate at shown in Fig. 2, substituted a curved plate d and a wedge block n is placed in the slot 0 and. is held in position by the heads or head portions of the bolts (2, and said block is provided ir its inner edge portion. with an arc-shaped recess in which the spoke closely fits.

The yoke member 0, plates (Z and (l and bolts 6 may be made of any ("lesir'edsize so as to adapt the device to wheels or spokes of any size, and changes in and modifications of tilt construction herein shown and described nay be made, within the scope of the appended claims, without departingfrom the s; irit of my invention or sacrificinn its advantages.

l'laving fully described my invention, what I clam as new and desire to secure by Letters Patent, is I 1. An att iching device, comprising a yoke member and a plate member, said yoke member being provided with a longitudinal slot, bolts passed through said slot and said plate member for i'lrawing the yoke and plate together, and said longitudinal slot being provided adjacent to the ends thereof and in the top and bottom Walls thereof with a plurality of notches or recesses in which said bolts fitand by means of which the rotation of said bolts is pre vented,

2. An attaching device, comprising a yoke member and a plate member, said yoke member being provided with a longitudinal slot, bolts passed tl'no'ugh said slot and said plate member for drawing the yoke and plate together, said longitudinal slot being provided adjacent to the ends thereof and m the top and bottom Walls thereof with a plurality of notches or recesses in which said bolts fit and by means of which the rotation of said bolts is Prevented, and a block placed in said longitudinal slot and held therein by said bolts for preventing the movement of said yoke on the article to which said attaching device is secured.

In testimony that I claim the foregoing as my invention I have signed my name in v presence of the subscribing witnesses this 17th day of January, 1916.

LUDWIG FRIEDRICH.
